The Cavitation Demonstration Trainer is designed to help trainees study and visualize the formation of bubbles that cause cavitation, using a Venturi tube. This system enables hands-on learning, allowing trainees to familiarize themselves with the fittings and gauges used to investigate the phenomenon. It also provides insights into the relationship between pressure and cavitation formation, offering practical understanding of this important fluid dynamics concept.
- The educational unit is a vertical panel to be fixed at the top of the main hydraulic unit.
- The educational unit is supplied with a thermometer, a rotameter, a gate valves for flow adjustment, a pressure reducing valve, a Venturi nozzle and manometer.
- Through the educational unit, the pressure energy of water is converted into kinetic energy and vice versa in the Venturi nozzle. Therefore, vapor bubbles form in the narrowest cross section.
- The Venturi nozzle is made of transparent plastic to allow visualizing of the flow processes.
- There are three pressure measuring points on the Venturi nozzle: at the inlet, at the narrowest point and at the outlet.
- The flow rate and the pressures can be controlled by two ball valves which are located at the inlet and outlet of the pipe system.
- The flow can be read off a rotameter.
- The pressure distribution within the Venturi nozzle is displayed on three manometers.
- The temperature is measured directly upstream of the Venturi nozzle and is shown on the thermometer.
- The input pressure can be controlled using a pressure reducing valve.
